What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Southampton, NJ allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Southampton, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

Homes throughout Southampton, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Reaching this target in your blower door test in Southampton, NJ helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Southampton, NJ

For blower door test in Southampton, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Southampton, NJ energy code requirements.
